Each person in a large sample of German adolescents was asked to
indicate which of 50 popular movies they had seen in the past year.
Based on the response, the amount of time (in minutes) of alcohol
use contained in the movies the person had watched was estimated.
Each person was then classified into one of four groups based on
the amount of movie alcohol exposure (groups 1, 2, 3, and
4, with 1 being the lowest exposure and 4 being the highest
exposure). Each person was also classified according to school
performance. The resulting data is given in the accompanying
table.
Assume it is reasonable to regard this sample as a random sample
of German adolescents. Is there evidence that there is an
association between school performance and movie exposure to
alcohol? Carry out a hypothesis test using
𝛼 = 0.05.
Calculate the test statistic. (Round your answer to two decimal
places.)
𝜒2 =
Use technology to calculate the P-value. (Round
your answer to four decimal places.)

What can you conclude?
Reject H0. There is convincing evidence
to conclude that the proportions falling into the alcohol exposure
categories are not all the same for the three school performance
groups.Fail to reject H0. There is not
enough evidence to conclude that the proportions falling into the
alcohol exposure categories are not all the same for the three
school performance
groups. Reject H0.
